Ocean currents impact methane consumption
PhysOrg, 6 hours ago
Large amounts of methane - whether as free gas or as solid gas hydrates - can be found in the sea floor along the ocean shores. When the hydrates dissolve or when the gas finds pathways in the sea floor to ascend, the methane can be released into the water and rise to the surface. Once emitted into ...

PhysOrg, 6 hours ago
A University of Colorado Boulder and North Carolina State University-led team has produced the first atlas of airborne microbes across the continental U.S., a feat that has implications for better understanding health and disease in humans, animals and crops.
Electron transfer challenges common fluorescence technique
PhysOrg, 6 hours ago
Tryptophan is an amino acid, one of the building blocks of proteins. It is used extensively to study how proteins change their 3D structure, and also how they interact with other proteins and molecules. This is studied with a fluorescence technique called FRET, which measures the transfer of energy ...
Deep national history of immigration predicts wide cultural comfort displaying emotion
PhysOrg, 6 hours ago
If your home country is historically heterogeneous and you know it, crack a smile. People who live in countries built on centuries of migration from a wide range of other countries are more emotionally expressive than people in more insular cultures, according to research led by University of Wiscon...
Uranium isotopes carry the fingerprint of ancient bacterial activity
PhysOrg, 6 hours ago
The oceans and other water bodies contain billions of tons of dissolved uranium. Over the planet''s history, some of this uranium was transformed into an insoluble form, causing it to precipitate and accumulate in sediments. There are two ways that uranium can go from a soluble to an insoluble form:...
Plausibility of the vibrational theory of smell
PhysOrg, 6 hours ago
The vibrational theory of olfaction explains several aspects of odorant detection that theories based purely on receptor binding do not. It provides for additional selectivity through receptors that are tuned to specific vibrational bands of the odorants they bind, and also through the subsequent co...
Research highlights the importance of ''self-DNA'' for maintaining diversity among species
PhysOrg, 6 hours ago
In natural plant communities, diversity is maintained by limits set on each plant by itself. This involves a detrimental effect of self-DNA (DNA from the same species released during decomposition) on the plant''s and its offspring''s growth. New research finds that this process not only regulates p...
Team studies intricacies of marine snow formation in the Gulf of Mexico following Deepwater Horizon oil spill
PhysOrg, 6 hours ago
Five years ago today, the Deepwater Horizon (DWH) oil rig exploded in the Gulf of Mexico. Since then, scientists have continued to study the effects of the largest environmental disaster in the history of the petroleum industry.
Necessity at the roots of innovation: The scramble for nutrients intensifies as soils age
PhysOrg, 6 hours ago
Confronted by extreme scarcity of nutrients in an Australian dune ecosystem, the leaves of different plant species converge on a single efficient strategy to conserve phosphorus, an essential nutrient. But it is a different story underground, say researchers, including Ben Turner, staff scientist at...
Decreasing biodiversity affects productivity of remaining plants
PhysOrg, 6 hours ago
When plant biodiversity declines, the remaining plants face diminishing productivity, say scientists in study published April 20 in the journal Proceedings of the National Academy of Sciences.
